Noise Reduction in Cooling Systems

When performances are silent

Not only do civil and urban contexts prefer cooling systems and low-noise technical solutions: even industries are increasingly sensitive to this issue. Some of the possible solutions are low-speed fans and sound-absorbing technical features.

Variable-speed fans, controlled by inverters, adjust the airflow according to the thermal load.

In sensitive locations, acoustic barriers and modular silencers are commonly adopted. Noise reduction in a cooling system involves three main areas: aerodynamics, components, and layout.

During the design phase, the use of selection and configuration software makes it possible to compare different solutions—chillers, cooling towers, adiabatic coolers, or dry coolers—by simulating their seasonal performance and heat loads. These digital tools also estimate energy and water consumption and help optimize system sizing.

Noise reduction in industrial coolers

In civil and urban contexts (but not only), strict compliance with noise limits is increasingly required: environmental standards such as ISO 3744 define how to measure the noise of machinery.

Offices, schools, public buildings and hospitals use air-conditioning or combined heat and power systems (with attached coolers) that have to meet certain standards. Industrial processes also increasingly require this.

Sound-Absorbing Solutions in Cooling Technologies

Special selection and noise reduction solutions on cooling systems

Reducing noise emissions is not a problem: simply view, select and configure a cooling tower or adiabatic cooler with simple and effective technical solutions:

  • fans with special profiles
  • motors with reduced speeds,
  • PLCs to optimise operating hours and frequency.
  • And in the specific case of evaporative towers, sound-absorbing hoods.

Advantages of low-noise solutions

  • Healthy working and living environment.
  • The peace of mind of complying with increasingly stricter regulatory requirements.
  • No risk of loss of efficiency or performance.
